Yeah I know that, but Anker often provides discounts of the order of 20% so unless you're suddenly made aware of it and can't wait you need never pay full price. Like the Powerhouse I don't think there's been more than 2 months pass without a discount. The current Powerhouse is version 2, they took feedback about the display from the original, within a few months (I think v2 was 4 months later). Same with Nebula Mars, I expect the brave early adopters will find the big initial issues, v2 will be better, then the lesser issues addressed in v3. Then there will be a discount for v3. That whole wait is likely 6 months. Most likely is a tweak of brightness up or size down and bigger battery. If its USP is portable projects on big far surface then that calls for brightness up (if it needs) or size down (if its bright enough) and a longer battery life.

This is a supply and demand problem. I think USB-PD laptops will pull a demand which a pocketable portable charger cannot safely meet.

Then there is the obvious gap in products which limit demand, like the Powerhouse is so physically heavy it calls for car-camping and it was not designed to be recharged by a car, then its for long off-grid near-car situations and it would be better with a solar charger option (I think unregulated to lower cost) so if they put that lot together it would pull a lot more demand and cause innovation.

Powerhouse, and the Nebular Mars also have a future together, one lets you have lots of power off-grid camping and the other gives you something to use all of that power. Currently they are significantly incompatible apart from the AC, but I'm sure a future USB-PD input Nebula can benefit from a future USB-PD output Powercore.

You need the soon to be released AirPin Pro app update for AirPlay to work with iOS11. AirPin is bundled with the Mars. I got it from the author (I bought it for Amazon Firestick TV) and it works. None of the non Apple solutions will ever work for legal software, which is not allowed to include Apple's FairPlay DRM. Not sure, there is an APK with a crack out there.

Better options for cheaper are to be had on Amazon. Plus with no sign of replacement or refund from Anker regarding the Nebula why would I buy a tripod? I already have a camera tripod that would work just fine if I ever get a replacement or refund to purchase another in the future.
